 ### Fixed
 
+- **fix(providers/llm7):** add `llm7` to the executor registry (`open-sse/config/providerRegistry.ts`). The provider was advertised in the dashboard catalog but missing from the executor table, so every connection test failed with a credential error. Now routes through the standard OpenAI-compatible `https://api.llm7.io/v1/chat/completions` endpoint with optional bearer auth. (#2361)
+- **fix(providers/cohere):** switch the Cohere upstream from `https://api.cohere.com/v2/chat` (native shape) to `https://api.cohere.com/compatibility/v1/chat/completions` (OpenAI-compatible). The native endpoint returned `{ message: { content: [...] } }` which the combo test validator could not read, surfacing as `Provider returned HTTP 200 but no text content.` (#2360)
+- **fix(combo/dispatch):** add defensive `typeof target.modelStr === "string"` guards around the LKGP fallback findIndex and the combo test target builder. Combo entries whose `modelStr` failed to resolve at routing time (regression after #2338 added per-account LKGP) used to crash the request with `TypeError: e.startsWith is not a function`; we now surface a clean error instead. (#2359)
+- **fix(rate-limiter):** Redis is now opt-in. When `REDIS_URL` is unset, the rate limiter and API-key auth cache fall back silently to the in-memory store instead of spamming `connect ECONNREFUSED 127.0.0.1:6379` for every request. Connection-error logging is also deduped so docker logs no longer flood under sustained outage. Single-instance deployments work out of the box; multi-instance deployments continue to use Redis when `REDIS_URL` is provided. (#2357)
 - **fix(auto-routing):** stop the `ReferenceError: getSettings is not defined` 500 that every `auto` / `auto/*` request raised. `src/sse/handlers/chat.ts` called the bare `getSettings` symbol without importing it; replaced with the already-imported `getCachedSettings` (same shape, plus the auto-routing hot path benefits from the cache). (#2346)
 - **fix(combo/validator):** treat upstream responses carrying a non-empty `reasoning_content` (or `reasoning`) field as valid output, even when `content` is null. Reasoning models like `moonshotai/Kimi-K2.5-TEE`, `zai-org/GLM-5-TEE`, and the QwQ family put their answer in `reasoning_content` only — the quality validator was rejecting them with `502: empty content` and triggering unnecessary combo fallbacks. (#2341)
 - **fix(docker):** the Dashboard Docs viewer now actually has documents to show. `.dockerignore` was hiding every file under `docs/` except `openapi.yaml`, so the in-product `/docs/*` viewer threw `ENOENT: no such file or directory, open '/app/docs/...'` for every page. We now ship the ~5 MB English markdown tree and still exclude the ~45 MB of translations/screenshots/raster diagrams that were the original optimization target. (#2348)
